Internal vs. External Validity (VCE Psychology)

When a study is said to be "Valid"....

• It is thought to measure what it was supposed to measure

• it is thought that the same or similar results should be achievable if repeated

• The DV is supposed to have the desired impact on the IV

• it is thought to be ineffective

The two general categories of validity are:

• High or Low

• External and Internal

• Ecological, Construct

• Temporal, Cultural

a measure of whether data can be generalized to other situations outside of the research environment they were originally gathered is called:

• external validity

• internal validity

• ecological validity

• none of the answers are correct

a measure of whether results obtained are solely affected by changes in the variable being manipulated (i.e. by the independent variable) in a cause-and-effect relationship.

• Internal Validity

• External Validity

• Cross-Cultural Validity

• All of the above

It is unlikely for any study to be completely valid and reliable.

• True

• False
